Stephen Davis is the product manager and director of building science for Quadrant Performance Materials. Quadrant is a spray foam insulation manufacturer that produces the EnvironSeal line of spray foam. Stephen has been working in the industry for the past 25 years and has always offered himself as a resource for all questions regarding spray foam, from building science to manufacturing and installation. I decided to take him up on his offer and it was wonderful to catch up, learn more about him, and to ask more questions about spray foam insulations in general.  Stephen Davis on LinkedIn Quadrant Performance Materials
